Questions 6

Refer to the exhibits.

Exhibit 1

Exhibit 2

Switch-1 and Switch-2 are configured to provide VRRP in VLAN 2. The default gateway for VLAN 2 is set to the VRRP virtual IP. Client-1 in VLAN 2 cannot ping its default gateway.

Based on the exhibits, what can administrators determine?

Options:

A.

The VRRP preempt delay time has not yet expired, and administrators should try to ping the gateway again in several minutes.

B.

Switch-1 and Switch-2 have the same virtual router ID. The conflict interferes with connectivity.

C.

Preempt mode is enabled on both Switch-1 and Switch-2, so the Master role continues to alternate between them, and the pings go astray.

D.

This is the expected behavior, and Switch-1 should still be able to route traffic for Client-1.

Questions 16

Refer to the exhibit.

The access layer AOS-Switches currently run DHCP snooping on VLAN 2 and connection rate filtering on edge ports. They are at default settings for ARP protection. A network administrator then enters these commands on each of the access layer switches:

Switch(config)# arp-protect vlan 2 Switch(config)# arp-protect

Which behavior accurse?

Options:

A.

The switches will forward legitimate traffic and prevent ARP poisoning attacks, but interfere with connection rate filtering.

B.

The switches can now prevent ARP poisoning attacks and do not interfere with legitimate communications.

C.

The switches can prevent ARP poisoning attacks, but legitimate communications with VLAN 2 could also be disrupted.

D.

The switches will not apply ARP protection due to interference from DHCP snooping, so the commands have no effect on current behavior.
